Pomona has some of the oldest residential housing in the Inland Empire, and that history sits in the walls and under the floors. Many homes near downtown and in the historic neighborhoods were built between the 1920s and 1960s, so galvanized steel supply lines, cast iron drain pipes, and clay tile sewer laterals installed decades before modern codes are still in service. Even the city's 1970s and 1980s neighborhoods are now approaching the end of their service life, and the region's clay-heavy soils and very hard water accelerate every type of failure.
Galvanized pipe corrodes from the inside out, so it narrows and rusts long before it leaks, which shows up as low pressure at multiple fixtures and rust-colored water. Cast iron drains develop rough interiors and rust-through holes that catch debris and leak under slabs. And older copper slab lines pinhole as the expansive clay soil moves and the mineral-heavy water etches the pipe from within. As a plumbing company serving Pomona, we camera-inspect first, then recommend cleaning, repair, or replacement based on what the line actually needs.

Answers to what Pomona homeowners ask us most.
Yes. California Plumbing Pros handles urgent Pomona plumbing around the clock, including burst pipes, sewer backups, flooding, and no hot water. Call (800) 390-6351 any time.
Yes. Pomona's water tests in the very hard range, typically between 200 and 300 milligrams per liter of dissolved minerals, well above the threshold that defines very hard. That mineral content accelerates scale buildup in water heaters, pipes, and fixtures. See water heater repair.
Often, yes. Many homes near downtown and in the historic neighborhoods were built between the 1920s and 1960s with original galvanized steel supply lines. Galvanized pipe corrodes from the inside out, so low pressure at multiple fixtures and rust-colored water are signs a repipe is due. See repiping.
Pomona sits on expansive clay soils that swell with moisture and contract when dry, stressing the copper pipes embedded beneath concrete foundations. Homes built from the 1960s through the 1980s are now in the window where pinhole leaks appear, and hard water speeds up the process. See slab leak repair.
Yes. Along with Pomona, we help homeowners in Claremont, La Verne, San Dimas, Montclair, Chino, Chino Hills, Ontario, Covina, Glendora, Walnut, Diamond Bar, and other nearby communities.
Yes. When a camera inspection shows the pipe still has enough structure, trenchless pipe lining can seal cracked clay or cast iron laterals from the inside and avoid tearing up driveways, patios, and mature landscaping.
